WASHINGTON -- A proposal by Democrat Hillary Rodham Clinton would provide $300 million a year in increased government funding on breast cancer research, focusing on treatment and exploring possible genetic and environmental triggers for the disease.

The presidential hopeful and former first lady discussed her plan with talk show host Ellen DeGeneres on her television show, which was scheduled to air Monday. As president, Clinton told DeGeneres, she would set a goal of finding a cure for the disease within 10 years.

Clinton's plan would increase funding for breast cancer research and treatment through programs at the National Institutes of Health, the National Cancer Institute, and the Department of Defense Congressionally Directed Medical Research Program.

It would also help more low-income women gain access to screenings like mammograms by making them more affordable. Among other things, she would eliminate Medicare co-payments for mammograms.

Clinton also planned to propose a new program to explore racial disparities in diagnosis and treatment of the disease.

About 40,000 women died of breast cancer in the United States in 2007, and some 240,000 new cases were expected to be diagnosed this year.
